DESCRIPTION
P3000 is a microprofile passive hybrid module for
applications where reinforced insulation is required.
It features fully vacuum encapsulated construction
using materials conforming to UL94V-0 flammability
requirements. The part is compliant with RoHS
Directive 2002/95/EC, and suitable for lead-free
and conventional placement and reflow.
P3000 performs the functions of reinforced safety
barrier (3750Vrms), telephone line matching and 2-4
wire conversion. This component is designed
specifically for high speed full-duplex data
transmission where very low levels of distortion are
required. High performance is achieved by realizing
a very low noise floor at the receive port even when
the power sourced at the transmit port is high.
Circuit simplification is readily achieved as the
transmit, receive and line ports are fully floating and
galvanically isolated from each other.
P3000 is readily matched to complex reference
impedances. The transmit and receive frequency
responses are very flat (i.e. negligible 'twist') when
matched to complex impedances.
For best operation the module requires a transmit
drive from a high-quality low-impedance source
(«10Ω), and a high impedance receive load (47kΩ
nominal). These impedances may be directly
provided by datapumps.
P3000 is also useful for voice applications
requiring 2-4 wire conversion as its port
impedances are particularly suitable for CODECs.
P3000 is certified to IEC 950 and UL 60950.
P3000 is a UL Recognized Component, and is
supported by an IEC CB Test Certificate.
